A process for producing a catalyst comprising zeolite and oligomeric silica with high mechanical resistance, which no longer requires a separation step of the zeolite crystalline phase from the suspension obtained at the end of the synthesis Providing a method. A tetra-alkylorthosilicate is added to a suspension resulting from the synthesis of a zeolite by hydrothermal treatment at a self-generated pressure of a reagent mixture containing tetra-alkylammonium hydroxide as a template, if necessary, and rapidly A process for producing a zeolite catalyst in the form of microspheres, comprising drying and calcining the product resulting from the drying, comprising high zeolite, zeolite and oligomer silica.
